We introduce a model of product development in a firm. Our model describes the process as a multi-stage contest (i.e., race) with an endogenous length (with one stage or two stages) between two workers. We model the payments to workers from the new product using the normatively appealing Nash...

In this paper we analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive...

It is shown that asymmetry in Ramp;D efficiency between firms is an important factor determining feasibility of the preemption and attrition scenarios in competitive Ramp;D with time to build. Scenarios of attrition and preemption games are most likely to occur when competitors have similar...

We consider the problem of bargaining over the disclosure of interim research knowledge between two participants in an R&D race for an ultimate, patentable invention. Licence fee schedules that are functions of the amount of knowledge disclosed, by the leading to the lagging agent, are examined...

We analyze an Open Innovation process in a Cournot duopoly using a differential game approach where knowledge spillovers are endogenously determined via the R&D process. The game produces multiple steady states, allowing for an asymmetric solution where a firm may trade off the R&D investment...

This paper shows that, if countries are farsighted when deciding whether to defect from a coalition, then the implementation of cleaner technologies may jeopardize the chances of reaching an international environmental agreement. The grand coalition may be destabilized by the implementation of...

This paper analyzes moral hazard in market entry competition between externally funded firms. A finite number of entrepreneurs seek to advance their promising yet loss-making startups into a profitable market. Market entry requires a breakthrough opportunity, which may be obtained at a fixed and...

The paper analyzes a dynamic model of R&D investment with inter- and intrasectoral R&D spillovers, in which the profitability of an invention in one sector increases if there is an innovation in another sector. Interpreting intrasectoral R&D spillovers as a measure of intellectual property...

We study a buyer's optimal investment strategy for new technologies when costs evolve stochastically and are private information to the suppliers. In a continuous time setting, we show how the asymmetric information on the stochastic variables leads to delays in investment compared to the real...

In recent years Open Innovation (OI) processes have been receiving growing attention from the empirical and theoretical economic literature, where a debate is taking place on the aspects of complementarity or substitutability between internal R&D and OI spillover. By means of a differential game...
